Farmers Reservoir and Irrigation Company <br />July 14, 2009 (UPDATED July 22, 2009) <br />Page 4 of 8 <br />Agenda Item 10 <br />Alternative No. 2- Replace the Upstream Outlet Gates Only: This alternative would <br />meet some of the Company's objectives by replacing the outdated upstream outlet gates <br />and allowing upstream operations of the reservoir. It would not include any repairs to the <br />aged steel-lined conduit section. Given the progression of degradation of the outlet pipe, <br />it is believed that these sections will continue to deteriorate. Failure of the outlet conduits <br />could result in failure of the dam, forcing the Company to drain the reservoir. The <br />estimated cost of this alternative was $630,000. <br />Alternative No. 3- Repair the Outlet Conduits Only: This alternative would involve <br />replacing the steel-lined section of the outlet conduits while leaving the upstream outlet <br />gates in their current condition, so the Company would still not have reliable upstream <br />operators. Given this alternative, the Company would continue to control flows using the <br />downstream gates. As the upstream gates have reached their useful life, it is expected that <br />in the near future, the gates will fail, leaving the Company dependent solely on the <br />downstream gates for safety and operations. This could create a potentially unsafe <br />condition. Under emergency conditions, the Company could be forced to drain down the <br />reservoir and replace the upstream gates. The estimated cost of this alternative was <br />$128,000. <br />Alternative No. 4(SELECTED) - Replace the Upstream Outlet Gates and Repair the <br />Outlet Conduits: This alternative consists of replacing the upstream outlet gates and <br />repairing the steel-lined section of the outlet conduits. This alternative would meet all of <br />the Company's objectives by replacing the outdated upstream outlet gates and allowing <br />upstream operations of the reservoir. It also addresses the problem with the aged steel- <br />lined conduit section and will enable the Company to operate flows through the system in <br />a safe environment. The estimated cost of this alternative was $698,000. <br />The Company selected Alternative No. 4 because it best meets the objectives of <br />continued safe operations of the dam, allows all of the components of the work to be <br />completed jointly, thereby saving money. During this portion of the Project, the reservoir <br />will be drained down to facilitate the construction of the gates and the replacement of the <br />44-inch steel-lined section of outlet conduit. The Company will remove the existing gates <br />and operators, install two new slide gates, install new hydraulic operators along the <br />upstream face of the dam, ~install a new gate control house, run power and a SCADA <br />system to the gate house, and configure the system to facilitate both local operations at <br />Milton Reservoir and remote operations from the Company's office in Brighton. <br />The schedule for this portion of the Project is: State Engineer's Office (SEO) review <br />during July/August 2009, bid the Project in September 2009, start construction by the end <br />of September 2009, and complete construction by the end of December 2009. The cost <br />estimate is as follows: <br />
